New kitchen sink issue

Hi all, newbie here. I recently had my kitchen sink replaced and the new one is smaller than the old one. They are both 22" x 33", but apparently the old one was more rectangular and the corners on the new one are tapered. In other words there are now gaps in the corners of the countertop.

I was planning on redoing the laminate on the countertops in the near future, but do I now need to redo the entire countertop? Any ideas as to how I can make the existing countertop work with the new sink on the long term? Can filler pieces be tied into the countertop and then laminated over? Thanks.
